Iron nails are placed in copper sulphate solution. Write word equation of the reaction involved. |
Answer:
When iron nails are placed in copper sulphate solution, displacement reaction takes place in which iron displaces copper as iron is more reactive than copper. \[\begin{align} & CuS{{O}_{4}}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,+\,\,\,\,Fe\,\,\,\,\,\to \,\,\,\,FeS{{O}_{4}}\,\,\,\,\,\,\,\,\,+\,\,\,\,\,Cu \\ & \text{copper}\,\text{sulphate}\,\,\,\,\,\,\,\text{Iron}\,\,\,\,\,\,\,\,\text{Iron}\,\text{sulphate}\,\,\,\text{Copper}\,\,\, \\ \end{align}\]
